Detection system for remotely monitoring people in elevator and trapped person monitoring system

Abstract

The invention discloses a detection system for remotely monitoring people in an elevator. The detection system comprises a signal acquisition mechanism, an elevator Internet of Things terminal and an elevator Internet of Things platform, the signal acquisition mechanism comprises a plurality of voice and infrared sensors and a plurality of weighing sensors, and the voice and infrared sensors are installed at the four corners of a ceiling of an elevator car so as to detect voice signals and infrared signals in the car; the weighing sensors are installed at the four corners of the car bottom so as to detect load signals in the elevator; and the elevator internet-of-things terminal obtains the voice signals, infrared signals and load signals and transmits the signals to the elevator internet-of-things platform, and the elevator internet-of-things platform judges whether a person exists in the elevator or not according to the three signals so as to generate a person-in determining signal. Whether a person exists or not is judged through the voice and infrared sensors at the four corners of the ceiling and the weighing sensors at the four corners of the car bottom, the detection modes are diversified, and the detection accuracy is high. The invention further discloses a corresponding monitoring system for remotely monitoring people trapped in the elevator.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to the detection and monitoring of remote elevator trapped persons. Background technique [0002] At present, my country's elevators are developing rapidly. Both the annual output of elevators, the growth of elevators and the number of elevators in use are increasing at a great rate every year. [0003] With the continuous development of my country's economy and society, and the continuous advancement of urbanization, more and more public gathering places and residential quarters have installed elevators to facilitate the life and work of citizens. In the case of normal operation of the elevator, people in the building can be transported safely, comfortably and efficiently. However, how to carry out rescue safely and quickly in the event of a power outage or elevator failure has attracted more and more attention from the industry. [0004] However, the existing elevator trapping sys...

Problems solved by technology

[0004] However, the existing elevator trapping system generally can only judge whether there is a person through the original weighing system of the elevator. When the weighing system makes a mistake, it is easy to cause misjudgment and affect the safety of the system.
